I can not get rid of the shield. I have tried shooting at the sides of it with the gun, but the guns won't shoot upwards to the source of the shield. Can I get some more details on how to get rid of the shield other than "get in the gun and shoot at it".

it says on the booklet that you can bring lego star wars 1 characters in to lego star wars 2 but when i tried it said:locked save not found.Ive got the first game and completed it. How do i bring the characters from lego star wars1 to number 2 ?
